Despite the obvious benefits of directed mechanisms that facilitate efficient transfer skills, there is little critical evidence for teaching in nonhuman animals. Using observational and experimental data, we show wild meerkats (Suricata suricatta) teach pups prey-handling skills by providing them with opportunities to interact live prey. In response changing pup begging calls, helpers alter their prey-provisioning methods as grow older, thus accelerating learning without use complex...
Significance Humans are unique among animals in their willingness to cooperate with friends and strangers. Costly punishment of unfair behavior is thought play a key role promoting cooperation by deterring selfishness. Importantly, adults sometimes show in-group favoritism punishment. To our knowledge, study the first document this bias children. Furthermore, results suggest that from its emergence development, children’s costly shows favoritism, highlighting group membership provides...
Adults and children are willing to sacrifice personal gain avoid both disadvantageous advantageous inequity. These two forms of inequity aversion follow different developmental trajectories, with emerging around 4 years 8 years. Although is assumed be specific situations where resources distributed among individuals, the role social context has not been tested in children. Here, we investigated influence aspects on 4- 9-year-old children: (1) experimenter distributing rewards (2) presence a...
Humans involved in cooperative interactions willingly pay a cost to punish cheats. However, the proximate motives underpinning punitive behaviour are currently debated. Individuals who interact with cheats experience losses, but they also lower payoffs than cheating partner. Thus, negative emotions that trigger punishment may stem from desire reciprocate losses or inequity aversion. Previous studies have not disentangled these possibilities. Here, we use an experimental approach ask whether...
When confronted with inequality, human children and adults sacrifice personal gain to reduce the pay-offs of other individuals, exhibiting apparently spiteful motivations. By contrast, by non-human animals is often interpreted as frustration. Spite may thus be a uniquely motivator. However, date, no empirical study has demonstrated that psychological spite actually drives behaviour, leaving motivation for inequity aversion unclear. Here, we ask whether 4- 9-year-old reject disadvantageous...
Abstract The social intelligence hypothesis, which posits that the challenges of life in complex environments drive cognitive evolution, enjoys widespread theoretical and empirical support. Recent years have seen emergence a novel variant this suggesting cooperative breeding is associated with elaboration socio‐cognitive abilities. With hypothesis ( CBH ) rapidly gaining currency, time ripe for critical appraisal. Proponents argue leads to increased performance, calling upon motivational...
Adults and children show ingroup favoritism in their 3rd-party punishment of cooperative norm violations, suggesting that group loyalty importantly shapes enforcement cooperation. Ingroup additionally influences unfairness the 2-party ultimatum game, which people are directly affected by unfair behavior. However, directionality this relationship is unclear: In some cases, more forgiving unfairness, whereas others they less forgiving. Here we aim to disambiguate studying its origins...
Women tend to negotiate less than men, which-along with other well-documented interpersonal and structural factors-contributes persistent gender gaps in pay for equal work. Here, we explore the developmental origins of these differences negotiation. Across three studies (N = 462), investigated 6- 12-year-old girls' boys' perceptions negotiation (e.g., how common permissible it is negotiate) gave children opportunities resources themselves. These were hypothetical Studies 1 2 actual Study 3....
Research on children’s responses to preventive health behaviors during COVID-19 provides insights of both practical and theoretical importance: Understanding how children reason about is crucial for developing effective public-health campaigns. Moreover, the pandemic presented us with a unique natural experiment examining emerging sociomoral reasoning in face rapidly changing norms social practices. Here we summarize empirical findings from series experiments testing such as mask-wearing...
Third-party punishment of unfairness shows striking cross-societal variation in adults, yet we know little about where and when development this starts to emerge. When do children across societies begin pay a cost prevent unfair sharing? We present an experimental study third-party sharing N = 535 aged 5–15 from communities six diverse countries: Canada, India, Peru, Uganda, USA, Vanuatu. tested whether were more likely punish equal or selfish (maximally unequal) distributions between two...
Darwin never provided a satisfactory account of altruism, but posed the problem beautifully in light logic natural selection. Hamilton and Williams delivered necessary satisfaction by appealing to kinship, Trivers showed that kinship was not as long originally altruistic act conditionally reciprocated. From late 1970s present, theories particular have been supported considerable empirical data elaborated explore number other social interactions such cooperation, selfishness punishment,...
Human behaviour is influenced by social norms but can entail two types of information. Descriptive refer to what others do in this context, while injunctive ought be done ensure approval. In many real-world situations these are often presented concurrently meaning that their independent effects on difficult establish. Here we used an online Dictator Game test how descriptive and would influence dictator donations when independently one another. addition, varied the cost complying with norm:...
